BS EN ISO 17201-1:2018规定了一种方法，用于确定口径小于20 mm或爆炸装药小于50 g TNT当量的炮口爆炸声源能量。它适用于峰值压力小于1 kPa（相当于154 dB的峰值声压级）的距离。由该程序确定的源能量、源方向性及其光谱结构可以用作声音传播程序的输入数据，从而能够预测靶场附近的射击噪声。此外，这些数据还可用于比较不同类型枪支或同一枪支使用的不同类型弹药发出的声音。 交叉引用:IEC 61672-1ISO/IEC指南98-3IEC 60942GUM:1995ISO 9613-1IEC 61672-2ISO 80000-8ISO 10843ISO 17201-2ISO 17201-4ISO 17201-3ISO 17201-5ISO 3745ISO 9614-3ISO 3741ISO/TR 25417:2007ISO 1996-1:2016购买本文件时提供的所有当前修订版均包括在内。

BS EN ISO 17201-1:2018 specifies a method to determine the acoustic source energy of the muzzle blast for calibres of less than 20 mm or explosive charges of less than 50 g TNT equivalent. It is applicable at distances where peak pressures less than 1 kPa (equivalent to a peak sound pressure level of 154 dB) are observed. The source energy, directivity of the source and their spectral structure determined by this procedure can be used as input data to sound propagation programmes, enabling the prediction of shooting noise in the neighbourhood of shooting ranges. Additionally, the data can be used to compare sound emission from different types of guns or different types of ammunition used with the same gun.Cross References:IEC 61672-1ISO/IEC Guide 98-3IEC 60942GUM:1995ISO 9613-1IEC 61672-2ISO 80000-8ISO 10843ISO 17201-2ISO 17201-4ISO 17201-3ISO 17201-5ISO 3745ISO 9614-3ISO 3741ISO/TR 25417:2007ISO 1996-1:2016All current amendments available at time of purchase are included with the purchase of this document.
